<P>PROBLEM TO BE SOLVED: To provide a method for simplifying installation work to considerably shorten a construction period and to reduce a construction cost regarding an intake construction method effective for an intake of an intake facility or the like for condenser cooling water of a thermal-nuclear power plant. Ž<P>SOLUTION: An intake unit 3 comprising a caisson 4, a pneumatic lid 15 partitioning the inside of the caisson 4 into two sections, and working cylinders 18, 18 which are erectly arranged in the upper part of the pneumatic lid 15, and embedded with pneumatic apparatuses is manufactured on the ground, and the intake unit 3 is transported by sea and installed on a rock bed 30 of the seabed in an area of site sea. In this state, concrete is placed in the outer peripheral section of the caisson 4, and the working cylinders 18 are used to compress air in a space 14 at the lower side of the pneumatic lid 15 by the pneumatic apparatus. In this state, concrete is placed in an inner peripheral section of the space 14. The working cylinders 18 are then removed, and the rock bed 30 is drilled toward the space 14 from the inside of a seabed intake tunnel 25 to connect the seabed intake tunnel 25 to the space 14. The pneumatic lid 15 is then removed, and an opening of the caisson 4 is closed with a lid. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
